    Abstract: PCT No. PCT/EP93/02851 Sec. 371 Date Apr. 21, 1995 Sec. 102(e) Date Apr. 21, 1995 PCT Filed Oct. 15, 1993 PCT Pub. No. WO94/10281 PCT Pub. Date May 11, 1994There are described the use of copolymers obtainable by free-radically initiated copolymerization of monomer mixtures comprising (a) 60-99% by weight of 1-vinylpyrrolidone, 1-vinylimidazole or mixtures thereof, (b) 1-40% by weight of nitrogen-containing, basic ethylenically unsaturated monomers in the form of the free bases, in the form of salts or in quaternized form, and optionally (c) up to 20% by weight of other monoethylenically unsaturated monomers, as detergent additives for inhibiting dye transfer during the wash, detergents which contain such polymers, and polymers which are obtainable by free-radically initiated polymerization of (a) 1-vinylpyrrolidone, 1-vinylimidazole, 1-vinylimidazolium compounds, or mixtures thereof, and optionally (b) other nitrogen-containing, basic ethylenically unsaturated monomers in the form of the free bases, in the form of the salts or in quaternized form, and/or (c) other monoethylenically unsaturated monomers, in an aqueous medium in the presence of water-soluble proteins and a process for the preparation of the polymers by polymerising the monomers (a) and optionally (b) and/or (c) in an aqueous medium in the presence of water-soluble proteins using from 0.5 to 400 parts by weight of protein per 100 parts by weight of monomer used in the polymerization.

    Abstract: The present invention relates to low-foam surfactant mixtures of the general formula (I) where R, Ra, R1 and R2, l, n and m have the meaning given in the description and the claims, and to the production thereof. For example, R=C13-alkyl, Ra=H, l=5, m=22, n=1, R1=methyl and R2=C6-C14-alkyl. The surfactants are suitable for detergent and cleaner formulations.
